David,
          As one who used to operate an original Sprengnether unit prior to
leaving New Zealand. You have done a beautiful job of a replica !!  well done!
I am seriously envious  ;)   I dont have the workshop or engineering skills
to pull that off.
    But I still have to build a LP unit somehow.  After many years of no 
operations
since moving to Australia I am finally up and running again.  At the moment 
just
using a 8Hz geophone donated by Pete Rowe.  Thanks mate  :)

cheers
Dave Nelson
Sydney
